Description

Die Erfindung betrifft ein Gargerät mit einen Garraum, einer Heizung, einem Umwälzsystem, einem Dampferzeuger und einem Meß- und Regelsystem, verbunden mit der Heizung, dem Umwälzsystem und dem Dampferzeuger.The invention relates to a cooking appliance with a cooking space, a heater, a circulation system, a steam generator and a measuring and control system connected to the heating, the Circulation system and the steam generator.

Solche bekannten Gargeräte sind unökonomisch, da sie ins­ besondere zum einen eine groß ausgelegte Heizung aufwei­ sen, die nur in seltenen Fällen komplett ausgenutzt wird, und zum anderen keine Abwärme nutzen.Such known cooking devices are uneconomical because they ins in particular, a large heating system which is only fully used in rare cases, and secondly, do not use waste heat.

Es ist daher eine Aufgabe der gegenwärtigen Erfindung, das gattungsgemäße Gargerät derart weiterzuentwickeln, daß es die Nachteile des Stands der Technik überwindet, das heißt insbesondere eine optimierte Energieregelung aufweist.It is therefore an object of the present invention that Generic cooking device to evolve such that it overcomes the disadvantages of the prior art, that is in particular has an optimized energy control.

Diese Aufgabe wird erfindungsgemäß durch ein Energiespei­ cher- und Energieentnahmesystem, verbunden mit dem Meß- und Regelsystem, gelöst.According to the invention, this object is achieved by an energy supply and energy extraction system connected to the measuring and control system, solved.

Dabei kann erfindungsgemäß vorgesehen sein, daß das Ener­ giespeicher- und Energieentnahmesystem einen Energiespei­ cher umfaßt, der über eine Heizung, vorzugsweise in Gar­ phasen, die keine oder wenig Energie benötigen, und/oder Garpausen, und/oder über Abwärme, wie Wärme von Abluft und/oder überschüssigem Dampf, mit Energie aufladbar ist.It can be provided according to the invention that the energy storage and energy extraction system an energy storage cher comprises of a heater, preferably in Gar phases that require little or no energy, and / or Breaks in cooking, and / or waste heat, such as heat from exhaust air and / or excess steam that can be charged with energy.

Die Erfindung sieht dabei vor, daß der Energiespeicher ein Material umfaßt, das zur Wärmespeicherung geeignet ist und/oder bei einer Phasenumwandlung latente Wärme ver­ braucht oder freisetzt.The invention provides that the energy storage Includes material that is suitable for heat storage and / or latent heat during a phase change needs or releases.

Das Material kann ein Metall, ein Salz, ein Polymer, Was­ ser, Dampf und/oder überhitzten Dampf gemäß der Erfindung umfassen. The material can be a metal, a salt, a polymer, what water, steam and / or superheated steam according to the invention include.  

Erfindungsgemäß bevorzugt ist, daß zumindest der Energie­ speicher des Energiespeicher- und Energieentnahmesystems platzsparend in einer isolierenden Haut des Gargeräts an­ geordnet ist.It is preferred according to the invention that at least the energy storage of the energy storage and energy extraction system space-saving in an insulating skin of the cooking appliance is ordered.

Ferner ist erfindungsgemäß vorgeschlagen, daß dem Energie­ speicher- und Energieentnahmesystem Energie durch Drosse­ lung vorhandenen Dampfes, Zugabe von Wasser und/oder Ver­ dampfen von Wasser an heißen Wänden entnehmbar ist, ins­ besondere zum Verdampfen von Wasser und/oder zur Beheizung eines Garprozesses.It is also proposed according to the invention that the energy storage and energy extraction system Energy through throttles existing steam, adding water and / or Ver vapor from water on hot walls can be removed, ins especially for evaporating water and / or for heating a cooking process.

Dem Energiespeicher kann erfindungsgemäß über zumindest eine Wärmeübertragungsfläche Energie entnehmbar sein.According to the invention, the energy store can at least a heat transfer surface energy can be removed.

Schließlich wird eine bevorzugte erfindungsgemäße Weiter­ entwicklung vorgeschlagen, bei der das Meß- und Regelsystem sicherstellt, daß die Unterhaltung eines Garprozesses stets höchste Priorität genießt.Finally, a preferred further invention Development proposed in which the measuring and control system ensures that the maintenance of a cooking process always has top priority.

Der Erfindung liegt somit die überraschende Erkenntnis zugrunde, daß durch den Einbau eines Energiespeicher- und Energieentnahmesystems, das mit dem in einem herkömmlichen Gargerät bereits vorhandenen Meß- und Regelsystem verbun­ den ist, einerseits die Heizleistung der Heizung für ein Gargut reduziert werden kann und andererseits Abwärme ge­ nutzt werden kann. Dabei kann ein Energiespeicher in Gar­ pausen, wie sie im Falle eines Chargenbetriebs stets an­ fallen oder durch den Garablauf bedingt sind, und/oder in aprioren Garphasen, in denen ein Garprozeß wenig oder kei­ ne Energie benötigt, mittels einer, gegebenenfalls zusätz­ lichen, Heizung, gesteuert über das Meß- und Regelsystem, nach einer Prioritätshierarchie zur Sicherstellung eines ungestörten Ablaufs eines Garprozesses, oder durch die Wärme aus dem Garraum austretender Abluft beziehungsweise austretenden überschüssigen Dampfes aufgeladen werden, um dann in hyperprioren Garphasen, in denen der Garprozeß viel Energie benötigt, mehr als die zum Heizen des Garguts installierte Heizung liefern kann, Energie aus dem Ener­ giespeicher entnehmen zu können.The invention is therefore the surprising finding based on the fact that by installing an energy storage and Energy withdrawal system that with that in a conventional Cooking device already connected measuring and control system that is, on the one hand, the heating output of the heating for one  Food can be reduced and on the other hand ge heat can be used. An energy storage in Gar pause, as in the case of batch operation fall or are due to the cooking process, and / or in a priori cooking phases, in which a cooking process little or no ne energy required by means of, if necessary, additional lichen, heating, controlled by the measuring and control system, according to a priority hierarchy to ensure a undisturbed sequence of a cooking process, or through the Exhaust air escaping from the cooking space or escaping excess vapor to be charged then in hyperprior cooking phases, in which the cooking process requires a lot of energy, more than that for heating the food installed heating can supply energy from the ener to be able to remove the memory.

Garprozesse mit hohem Dampfverbrauch können durch Verwen­ dung eines erfindungsgemäßen Gargeräts zudem, insbesondere zu Anfang, beschleunigt werden. Ist der Energiespeicher, beispielsweise, mit 2 kWh bemessen und wird seine Energie in den ersten zehn Garminuten entnommen, ergibt dies einen Leistungszuwachs von 12 kW, das heißt, daß dem Garprozeß bei einer Heizleistung von 9 kW in den ersten zehn Garmi­ nuten 21 kW zur Verfügung stehen.Cooking processes with high steam consumption can be extension of a cooking device according to the invention, in particular in the beginning, be accelerated. Is the energy storage, for example, rated at 2 kWh and will use its energy taken in the first ten minutes of cooking, this gives one Power increase of 12 kW, that is, the cooking process with a heating power of 9 kW in the first ten Garmi slots 21 kW are available.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der zwei Ausführ­ ungsbeispiele der Erfindung anhand von schematischen Zeichnungen im einzelnen erläutert sind. Dabei zeigt:Further features and advantages of the invention result from the following description, in the two versions Examples of the invention based on schematic Drawings are explained in detail. It shows:

Fig. 2 eine Schnittansicht durch ein alternatives Ener­ giespeicher- und Energieentnahmesystem zur Verwen­ dung in einem erfindungsgemäßen Gargerät. Fig. 2 is a sectional view through an alternative energy storage and energy extraction system for use in a cooking device according to the invention.

Wie Fig. 1 zu entnehmen ist, umfaßt ein erfindungsgemäßes Gargerät 1 einen Garraum 2, begrenzt durch Wände 3a und verbunden mit einem Ablauf 3b, eine Heizung 4 für Gargut, ein Umwälzsystem 5 für Gargut, bestehend aus einem Motor 5a, einem Umwälzer 5b und einem Strömungsführer 5c, einen Dampferzeuger 6, zur Befeuchtung des Garguts, umfassend Wasser 6a und eine Heizung 6b, eine Regeleinrichtung 7, die mit der Heizung 4, dem Umwälzsystem 5, dem Dampferzeu­ ger 6, einem Feuchtefühler 8, einem Temperaturfühler 9 sowie einem Energiespeicher- und Energieentnahmesystem 10 verbunden ist. Die Regeleinrichtung 7, die in konventio­ nellen Gargeräten lediglich die Aufgabe hat, Feuchtigkeit sowie Temperatur des Garguts und Beschwadungszyklen zu re­ geln, verfügt erfindungsgemäß über einen zusätzlichen Re­ gelkreis, der den Energiegehalt des Energiespeicher- und Energieentnahmesystems 10 regelt, wobei der verwendete Regelalgorithmus so gestaltet ist, daß die Unterhaltung des Garprozesses stets höchste Priorität genießt.As can be seen in FIG. 1, a cooking device 1 according to the invention comprises a cooking space 2 , delimited by walls 3 a and connected to an outlet 3 b, a heater 4 for food, a circulation system 5 for food, consisting of a motor 5 a, one circulator 5 b and a flow guide 5 c, a steam generator 6, for humidifying the product to be cooked, comprising water 6 a and a heater 6 b, a control device 7, with the heater 4, the circulation system 5, the Dampferzeu ger 6, a humidity sensor 8 , a temperature sensor 9 and an energy storage and energy extraction system 10 is connected. The control device 7 , which in conventional cooking devices only has the task of regulating moisture and temperature of the food and steaming cycles, has an additional control circuit according to the invention, which controls the energy content of the energy storage and energy extraction system 10 , the control algorithm used in this way is that maintaining the cooking process is always a top priority.

Das Energiespeicher- und Energieentnahmesystem 10 umfaßt dabei eine Heizung 10a und einen Energiespeicher 10b, bei­ spielsweise umfassend einen Metallblock mit einer zentra­ len Durchführung, die über ein Ventil 10c mit einer Was­ serzufuhr 10d verbunden ist und eine Wärmeübertragungsflä­ che 10e umfaßt. Dabei ist sowohl die Heizung 10a als auch das Ventil 10c mit der Regeleinrichtung 7 zur gezieltes Energieladung und Energieentnahme verbunden.The energy storage and energy extraction system 10 includes a heater 10 a and an energy storage 10 b, for example comprising a metal block with a central implementation, which is connected via a valve 10 c with a water supply 10 d and a heat transfer surface 10 e . Both the heater 10 a and the valve 10 c are connected to the control device 7 for targeted energy charging and energy extraction.

Das mit Bezug auf Fig. 1 beschriebene Gargerät 1 arbeitet beispielsweise wie folgt:The cooking appliance 1 described with reference to FIG. 1 works as follows, for example:

In aprioren Garphasen, in denen ein Garprozeß nur wenig oder keine Energie benötigt, in Be- und Entladephasen des Gargeräts 1 und in ablaufbedingten Garpausen sorgt die Regeleinrichtung 7 dafür, daß die Heizung 10a den Energie­ speicher 10b, der als Wärmespeicher fungiert, aufheizt. In prior cooking phases, in which a cooking process requires little or no energy, in loading and unloading phases of the cooking device 1 and in process-related cooking breaks, the control device 7 ensures that the heater 10 a heats the energy store 10 b, which acts as a heat store .

In hyperperioren Garphasen, in den der Garprozeß extrem viel Energie benötigt, mehr als die im Garraum 2 instal­ lierte Heizung 4 zur Verfügung stellen kann, speist das Energiespeicher- und Energieentnahmesystem 10 Dampf zu­ sätzlich in den Garraum 2 ein und reichert auf diese Weise das Garmedium mit Feuchte und Wärme an. Der Dampf wird dabei dadurch erzeugt, daß über die Wasserzufuhr 10d und das von der Regeleinrichtung 7 geöffnete Ventil 10c Wasser zugeführt wird, das bei Kontaktierung der Wärmeübertra­ gungsfläche 10e verdampft.In hyperperioren cooking phases in which the cooking process is extremely requires much energy, can provide as the instal profiled in the cooking chamber 2 Heating 4 available more, the energy storage and extraction system feeds 10 steam to additionally into the cooking chamber 2, and accumulates in this way the cooking medium with moisture and warmth. The steam is generated by supplying water via the water supply 10 d and the valve 10 c opened by the control device 7 , which evaporates when the heat transfer surface 10 e is contacted.

Das in Fig. 2 dargestellte Energiespeicher- und Energie­ entnahmesystem 20 umfaßt eine über eine Stromquelle 21a heizbare Heizung 21b, wobei das Beheizen über eine Regel­ einrichtung 17 und einen Schalter 21c regelbar ist. Der Energiespeicher an sich besteht aus zwei parallelen Ver­ bindungsrohren 22a, 22b zwischen denen eine Vielzahl von Rohren 22c verlaufen, wobei das Rohrsystem 22a, 22b, 22c Wasser 23 hermetisch abgeschlossen in einer bestimmten Menge umfaßt. Zur Energieaufnahme ist zwischen der Heizung 21b und dem Rohrsystem, nämlich dem Verbindungsrohr 22a, ein Wärmeleiter 24a vorgesehen, und zur Wärmeabgabe ist ein weiterer Wärmeleiter 24b zwischen dem Rohrsystem, näm­ lich dem Verbindungsrohr 22b, und einer Wärmeübertragungs­ fläche 25c vorgesehen. Im Falle der Energieentnahme fließt Wasser über die Wärmeübertragungsfläche 25c, das über eine Wasserzufuhr 25a und ein Ventil 25b zuführbar ist. Außer­ dem sind Temperaturfühler vorgesehen, nämlich ein Tempera­ turfühler 26a für den Energiespeicher und ein Temperatur­ fühler 26b für den Entnahmedampf.The energy storage and energy extraction system 20 shown in FIG. 2 comprises a heater 21 b that can be heated via a current source 21 a, the heating being controlled by a control device 17 and a switch 21 c. The energy storage itself consists of two parallel connecting pipes 22 a, 22 b between which a plurality of pipes 22 c run, the pipe system 22 a, 22 b, 22 c comprising water 23 hermetically sealed in a certain amount. For energy consumption between the heater 21 b and the pipe system, namely the connecting pipe 22 a, a heat conductor 24 a is provided, and for heat emission, another heat conductor 24 b between the pipe system, namely the connecting pipe 22 b, and a heat transfer surface 25 c intended. In the case of energy withdrawal, water flows via the heat transfer surface 25 c, which can be supplied via a water supply 25 a and a valve 25 b. In addition, temperature sensors are provided, namely a temperature sensor 26 a for the energy store and a temperature sensor 26 b for the extraction steam.

Das mit Bezug auf Fig. 2 beschriebene Energiespeicher- und Energieentnahmesystem arbeitet wie folgt:The energy storage and energy extraction system described with reference to FIG. 2 operates as follows:

Die Regeleinrichtung 17 regelt den Energie- beziehungswei­ se Wärmegehalt des Energiespeichers, nämlich ein Aufheizen des Wassers 23 im Rohrsystem 22a, 22b, 22c, durch Schalten des Schalters 21c und die Energie- beziehungsweise Wärme­ abgabe, nämlich eine Dampferzeugung, über das Ventil 25b. Diese Regelung geschieht unter Berücksichtigung des Gar­ prozesses, dessen Unterhaltung stets Priorität hat, und der Temperatur in dem Rohrsystem 22a, 22b, 22c sowie der Temperatur des erzeugten Dampfes, gemessen über die Tempe­ raturfühler 26a und 26b.The control device 17 regulates the energy or heat content of the energy store, namely heating the water 23 in the pipe system 22 a, 22 b, 22 c, by switching the switch 21 c and the energy or heat output, namely a steam generation, via the Valve 25 b. This regulation takes into account the cooking process, the maintenance of which always has priority, and the temperature in the pipe system 22 a, 22 b, 22 c and the temperature of the steam generated, measured via the temperature sensor 26 a and 26 b.

Das Rohrsystem 22a, 22b, 22c kann äußerst platzsparend in einer nicht gezeigten, isolierenden Haut eines Gargeräts untergebracht werden, wobei die Energieentnahme durch ein verschweißtes Parallelrohr ermöglicht wird. The pipe system 22 a, 22 b, 22 c can be accommodated in an extremely space-saving manner in an insulating skin (not shown) of a cooking appliance, the energy extraction being made possible by a welded parallel pipe.
